我正在尝试使用锻炼课程为家庭作业创建一个应用程序，该锻炼课程将根据执行某些锻炼所花费的时间来计算燃烧的卡路里数量。我的布局就像我想要的那样，模拟器运行正常，直到我输入最后一个（第三个）输入。我仍然是一个新手，我确信我的错误很简单。任何帮助深表感谢！！！
这是我的锻炼课程：
public class Workout {
private int totalCalories;
private float runningTime;
private float cyclingTime;
private float walkingTime;
public Workout( float r, float w, float c){
setRunning(r);
setWalking(w);
setCycling(c);
}
public void setRunning(float r)
{
runningTime=r;
}
public void setCycling(float c)
{
cyclingTime=c;
}
public void setWalking(float w)
{
walkingTime = w;
}
public float caloriesBurned(){
return runningTime * 350 + walkingTime * 100 + cyclingTime * 50;
}
}
这是我的MainActivity类：
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.text.Editable;
import android.text.TextWatcher;
import android.widget.EditText;
import android.widget.TextView;
public class MainActivity extends AppCompatActivity {
private Workout calCalc;
private EditText runEditText;
private EditText walkEditText;
private EditText cycleEditText;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
calCalc=new Workout(150.0f, 100.0f, 50.0f );
setContentView(R.layout.activity_main);
runEditText = (EditText) findViewById(R.id.amount_run);
walkEditText=(EditText) findViewById(R.id.amount_walk);
cycleEditText=(EditText) findViewById(R.id.amount_cycle);
TextChangeHandler tch = new TextChangeHandler();
runEditText.addTextChangedListener(tch);
walkEditText.addTextChangedListener(tch);
cycleEditText.addTextChangedListener(tch);
}
public void calculate() {
String runString = runEditText.getText().toString();
String walkString = walkEditText.getText().toString();
String cycleString = cycleEditText.getText().toString();
TextView caloriesBurnedTextView =
(TextView) findViewById(R.id.amount_calories);
try{
float runAmount = Integer.parseInt(runString);
float walkAmount = Integer.parseInt(walkString);
float cycleAmount = Integer.parseInt(cycleString);
calCalc.setRunning(150.0f * runAmount);
calCalc.setWalking(100.0f * walkAmount);
calCalc.setCycling(50.0f * cycleAmount);
float totalCalories = calCalc.caloriesBurned();
caloriesBurnedTextView.setText((int) totalCalories);
} catch(NumberFormatException nfe) {
}
}
private class TextChangeHandler implements TextWatcher
{
public void afterTextChanged(Editable e) {
calculate();
}
public void beforeTextChanged(CharSequence s, int start, int count, int after)
{
}
public void onTextChanged(CharSequence s, int start, int before, int after)
{
}
}
}
输入跑步，步行和骑行的3个区域后，会出现一个“计算”按钮，单击该按钮进行计算并输出燃烧的总卡路里。
这是我的activity_main.xml：
